GUT-OFT DEVICE FOR I'OKTDEIR-BOX'ESv Specification of Letters Patent.

Patented Apr. 4, 19116.

Application filed November 10, 1914.. Serial No. 871,419.

To all whom it may concern Be it known that I, GEORGE L. LILLY, acitizen of the United. States of America, residing at Jacksonville, inthe county of Duval and State of Florida, have invented new and usefulImprovements in Cut-Off Devices for Powder-Boxes, Medicine-Containers,and the like, of which the following is a specification.

This invention relates to improvements in cut-ofi devices for powderboxes, medicine containers and the like and has particular applicationto a measuring cut-off device.

In carrying out the present invention it is my purpose to provide adevice of the class described which may be readily applied to any powderbox or medicine container now 1n use and whereby the flow from thecontainer will be automatically cut 05 after the determined quantity hasbeen discharged.

It is also my purpose to provide a device of the class described whichwill be automatic in operation and which will embrace the desiredfeatures of simplicityfeiifihiency and durability coupled with cheapnessof cost in manufacture and marketing.

With the above and other objects in view, the invention consists in theconstruction, combination and arrangement of parts hereinafter set forthin and falling within the scope of the claim.

In the accompanying drawing; Figure 1 is a view in side elevation of apowder container equipped with a measuring cut-ofi' device constructedin accordance with the present invention. Fig. 2 is an enlarged verticalsectional view through the discharge spout of the powder container andthe cutofi device thereon showing the parts in normal closed position.Fig. 3 is a view similar to Fig. 2 showing the parts in the positionthey occupy when the powder is discharged. Referring now to the drawingin detail, 1 designates a powder container of any suitable or preferredconstruction. In the present instance, this powder container is providedwith an upwardly extending discharge spout 2 by means of which thepowder may be discharged from the container when the latter is inverted.

My improved cut-01f device 1s designated as an entirety at 3 and, in thepresent instance, comprises .a tube 4 designed to encircle the outer endof the spout 2 and of a cross sectional configuration corresponding tothat of the spout. In this instance, the tube 4 is substantiallyrectangular in cross section owing to the spout 2 being of this shape,and journaled in the opposite end Walls of the tube 4 and lying adjacentto the inner face of one of the side wall thereof is a rod 5, while acover plate 6 has one edge suitably secured to the rod 5. This coverplate is of cross and longitudinal dimensions slightly greater than thecorresponding dimensions of the tube 4 so that when the cover plate isin closed position it will overlap the outer edge of the tube toeffectively close the same. Also secured tothe rod 5 and extending intothe thbe 1 1n a plane at right angles to the cover plate 6 is a cut-offplate 7 of transverse and longitudinal dimensions equal to those of thetube and normally lying against the ad; jacent side wall of the tube andadapted to be moved across the tube when the cover plate 6 is swung toopen position. Secured to one end of the rod 5 and depending therefromat an angle to the vertical is an arm 8 and connected with the lower endof the arm 8 is a weight 9.

In practice, the cover plate 6 normally extends across the tube 4 and so.closes the spout 2. When, however, it is desired to discharge aquantity of the powder from the container, the latter is inverted and inthis movement of the container the weight 9 swings the arm 8 and rod 5with the effect to move the cover plate 6 out of the path of the powderand the cut off plate 7 across the path of the powder. In this movementof the plates the quantity of powder between the same is discharged andthe cutoff plate closes the tube 4, thereby preventing further dischargeof the powder. When the position of the container is reversed the weight9 again swings the arm 8 in the reverse direction and so reciprocatesthe cover plate and cut-off plate to normal positions so that the aboveoperation may be repeated when the container is again inverted.

From the foregoing description taken in connection with the accompanyingdrawing, the construction, mode of operation and manner of employing myimproved measuring cut-off device will be readily apparent. It will beseen that when the container is inverted to discharge the contentsthereof a predetermined quantity only of such contents is discharged.Although I have shown and described the device as particularly adaptedfor powder containers, I Wish it to be understood that the same is eually applicable to liquid medicine containers and in practice theplates 6 and 7 may be so connected as to be capable of relativeadjustment so that the quantity of material discharged from thecontainer may be varied in accordancewith the circumstances of theparticular case.

While I have herein shown and described one preferred form of myinvention by way of illustration, I wish it to be understood that I donot limit or routine myself to the precise details of constructionherein described and delineated, as modification and variation may bemade within the scope of the claims without departing from the spirit ofthe invention.

I claim:

A device of the class described comprising a tube angular in crosssection, a rod journaled in said tube at one end thereof lying parallelwith one of the walls of the tube, a

cover plate having one edge connected to said rod and normally lyingacross the adjacent end of the tube to close the latter, a cut-off plateconnected to said rod and projecting into said tube normally parallelwith the adjacent wall and arranged at right angles to said cover plateand movable across said tube in the movement of the cover plate to openposition, an arm connected to one end of said rod and dependingtherefrom at an angle to the vertical and a weight on the free end ofsaid arm acting to hold the cover plate and the cut-off plate in normalposition and to swing the same out of such position when the tube isinverted.

In testimony whereof I affix my signature in presence of two Witnesses.
